Tado TRV with white label thermostat

Third party integrations
1

Have anyone been able to integrate Tados TRV with a white label thermostat? I’ve seen that the Tado external thermostat are a rip off, and I was willing to see if anyone has been able to create an alternative mechanism to manage this maybe with the help of HA entities (although I don’t see at a first glance any HA Tado entity that could help for this purpose, considering that the regulation of Tado TRV temperature is only based on the internal Tado TRV temp sensor which is omega useless)

I bought these Tados like 1 year ago, when I was building my house, because I was completely naive in this topic and I wanted my plumber to set them up for me in the radiators with the right valves and all that. But I never dug enough to clearly find that they are a complete rip off by default. I’ve been lookikng in Github repos and I don’t see a lot of extra info about hacking these devices. They feel too closed to do anything worthy with them. I may return some of them maybe alleging warranty of something (they simply don’t meet the needs by any means).

But If I find a hacky solution to bypass all this with some whitelabel sensors, a new window of opportunities may open.

Are they wifi, zigbee or zwave? Or something else.

Not sure what the underlying protocol is but I do know that they have made it a proprietary system so off the shelf they can only pair with Tado internet bridge.

The tado° devices communicate via radio at 868 MHz using the IPv6 enabled “6LoWPAN” protocol. The advantage of using this protocol for the tado° wireless network, instead of Wi-Fi (2.4 and 5 GHz), is the extremely low power consumption combined with superior range inside buildings and through walls.

We have tado trv’s in very room of the house and don’t have an issue, in fact the house has never been more comfortable and fully adaptable to our needs and our gas bill is almost half What it was before hand.

We currently have the system as a native tado system and have that integrated to HA.

So although we have additional room temp sensors available in HA we don’t use them for the heating.

There is nothing to stop me using them however.

I could pair them to HA HomeKit and then you can reference any temp sensor available within home assistant.

Or similarly I could set up templates and automations within HA to command heat on and heat off via the api but referencing my own temp sensor and simply demand excessive temp via tado if that makes sense.

Either way they are perfectly usable and how much control and or accuracy you want probably comes down to how much effort you want to put in.

I personally don’t care much for stressing over the trv’s offset (I know a lot of people do) because it’s just a reading and once I set the system to the actual room temp we like in the schedules I don’t really care what the actual sensor reading is or has to be.

They are actually very accurate it’s just down to the inherent nature of them being so local to the heat source.

You could even generate a template to create a temp sensor and add or subtract from the reading based on the rise in temp from the heat source if you wanted.

On reading the other posts, and looking at integrations page, I wonder if @SirLouen is aware of the tado integration. Tado - Home Assistant

I’ve discovered the offset in the configuration, which has made things a lot better
Still the fact they are so closed, have made me dislike them a lot compared to other alterantives
The fact that they work for you, doesn’t make them better. You can buy the shittiest card in the world and still it takes you to work everyday.

But there are thermostats that just integrate better. I just bought them on a rush (no less than 9 heads TRV + the main thermostat with the shitty closed bridge)

I’m so disappointed now, a waste of money that I can barely control with HA (through an API, I hate API integrations)

Yeah, that is the first thing I did!

Although I could maybe create a script that uses an external thermostat and just try to correlate somehow by using a big offset in the Tado’s config. I would have to micromanage them by checking temperetures constantly and design a little table, for example: if external thermometer is at 23º set the Tado at 20º with an offset of -5ºC, if the thermo is at 20ºc Set the Tado to 25º with an offset of -5ºC. Very counterintuitive AFAIK.

Although I may end buying the friking “official Tado thermometer for some rooms” ($60 on offer for just a simple thermometer, the biggest rip off in the history)

I am somewhat confused by what it is you actually want.

Is it that you just want to rant about how much money you spent without beforehand doing any research on a relatively expensive product, and complain about the product in general.

Or is it that you are trying to find

In the above thread as far as I can see, I was the only one that hinted at different ways you could achieve a “hacky solution” and suggested a few:

There are many more but all require a little effort on your behalf. In fact within a matter of seconds I can find many automations that deal with the offset for example.

But instead of requesting more details on how these hacks that you were originally looking for may work or how you can achieve them you reply with comments like:

So may I suggest you consider what it is you want, is it just a rant or do you want to make the best of what you have already invested in?

Either way good luck with your quest moving forward.

So basically you set up your Tado’s with the Tado app and you are happy just like that?

Personally I did so, and I found that the radiators were not even heating, setting the TRV at top temperature (25ºc) so I had to offset like 3ºC to start seeing some difference (now with the offset I have to admit that it’s more feasible, but not super amazing at least for the price I’ve paid for)

About what you say about thermometers, the problem is that there is no “direct API” to the % of opening of the Tado valves. If I could set like 0%, 10%, 50%, 75% 100% of opening, then I could be referencing an external temperature sensor to such API.

But all you have with Tado is the degrees of the valve as a reference, which is not % by any means.

Maybe I’m having difficulties to grasp an understanding on how I could correlate an external temperature sensor to the internal sensor of the Tado themselves.

The problem is that for example my external Temp sensor could be outputting 22ºC and the Tados 25ºC but then the external temps ensor could be outputting 18ºC and the Tados 22ºC. And the external 15ºC and the Tdos 20ºC so as you see the correlation is not linear, which makes things very weird. And if you think twice, using an external sensor this way, would be the same as averaging an offset, and simply setting the offset in the app (which I did to -3ºC which is not the average, but I think is enough just yet)

With the propietary Tado temp sensor, it adjusts the valve accordingly, because it must have % readings of the valve itself. But since they have a closed infrastructure, doing feels extremely complex from my point of view.

Maybe you can think on a better solution, but I’m a little dazed with this situation, and this is the cause of my ranting.
